Skinbetter Science Ampra Volumizing SerumThink of Ampra as a 'filler inspired' serum. While many serums moisturize the surface, Ampra is a volumizing face serum designed to target volume loss, the process where skin begins to look thinner or ' hollowed out' as we age. It uses a unique 'macro' Hyaluronic Acid ( HA) to physically help the skin look fuller from the outside in.
